Well the simple answer is it's not stable enough. If you don't mind adding it every day. As far as I can tell it is OK in a pinch, but wont hold very long. Also it can also change the
nutrient composition every time you add a additive. So the less you the add the better. There are thousands of types of "acids" and or "bases"there not all the same. The price difference is just not worth the headaches as far as I can see. In fact its much more expensive from my experience.
